Abstract

The utility model belongs to the field of molten iron desulfurization equipment and particularly relates to a double-nozzle rotary desulfurization spray gun. The double-nozzle rotary desulfurization spray gun comprises a flange (1), a spray pipe (2), a framework (3) and a refractory material layer (4), wherein the framework (3) and the refractory material layer (4) are fixedly arranged on the spray pipe (2); one end of the spray pipe (2) is fixedly connected with the flange (1); the spray pipe (2) is arranged in the refractory material layer (4); two nozzles (5) are formed in the other end of the spray pipe (2); a rotating mechanism (6) is arranged on the flange (1); a protecting pipe (7) is fixedly sleeved outside the nozzles (5) of the spray pipe (2); and blades (8) are fixedly arranged on the outer sides of the refractory material layer (4). The mixing and stirring effect of molten iron and a desulfurizing agent can be improved, the floating track of carrier gas flow is changed, the desulfurization rate is improved, and the splashing strength is reduced.

Description

A kind of pair of spout rotation desulphurization spray gun
Technical field
the utility model belongs to the desulfurizing iron apparatus field, relates in particular to a kind of pair of spout rotation desulphurization spray gun.
Background technology
injection metallurgy typically refers to the fixed blowing process of widespread use in industry: spray gun is from furnace bottom, and furnace wall and furnace roof all remain static when jet in the molten bath.When spray gun when furnace bottom is upwards jetted, fixed blowing process is unique method, promptly spray gun need be fixed in the flame retardant coating of furnace bottom.When spray gun inserts winding-up from the furnace wall, generally also remain static.
spray gun blowing process has become one of main method of desulfurizing iron; But used fixed blowing process improvable place on kinetics mixing condition of decades more limited, be not easy further to improve desulfuration efficiency and the utilization ratio that improves sweetening agent.It is very big that high speed jet and molten iron rock the vibration that makes spray gun, when winding-up, need adopt fixedly spray gun of clamper, not only requires spray gun physical strength height, but also require jacking equipment that stronger supporting capacity is arranged.
Characteristics such as existing desulfurizing spray gun for pretreating molten iron all adopts the static spray gun of column type, and it is big that this type of spray gun exists sweetening agent splash intensity, and sweetening agent and molten iron mixed effect are poor, and desulfuration efficiency is low.
The utility model content
the utility model is intended to overcome the weak point of prior art and a kind of mixing effect that mixes that improves molten iron and sweetening agent is provided; Change carrier gas stream come-up track, the two spout rotation desulphurization spray guns that improve desulfurization degree and splash intensity is reduced.
for solving the problems of the technologies described above, the utility model is achieved in that a kind of pair of spout rotation desulphurization spray gun, and it comprises flange, jet pipe, is fixedly arranged on skeleton and refractory masses on the jet pipe; One end and the flange of said jet pipe are fixedly connected; Said jet pipe places within the refractory masses; The other end of said jet pipe is furnished with two spouts.
as a kind of preferred version, the utility model can be provided with rotating mechanism on said flange.
as another kind of preferred version, the utility model is with protecting tube at the spout external fixation of said jet pipe.
further, the utility model is fixed with blade in the outside of said refractory masses.
the utility model has carried out industrial test in the 65t ladle of desulfurization station, data show, can desulfurization degree be improved 20%~30%, reduces metal splash loss, and cooling reduces 50%.The utility model has improved the mixing of molten iron and sweetening agent and has stirred, and has changed the track of carrier gas stream come-up, and bubble diminishes, and ascent rate is slack-off, and sweetening agent and molten iron mix better, has improved desulfurization degree and splash intensity is reduced.
Description of drawings
are described further the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Among figure: 1, flange; 2, jet pipe; 3, skeleton; 4, refractory masses; 5, spout; 6, rotating mechanism; 7, protecting tube; 8, blade.
Embodiment
are as shown in the figure, a kind of pair of spout rotation desulphurization spray gun, and it comprises flange 1, jet pipe 2, is fixedly arranged on skeleton 3 and refractory masses 4 on the jet pipe 2; One end and the flange 1 of said jet pipe 2 are fixedly connected; Said jet pipe 2 places within the refractory masses 4; The other end of said jet pipe 2 is furnished with two spouts 5.
the utility model can be provided with rotating mechanism 6 on said flange 1.When carrying out desulfuration operations,, can rotating mechanism 6 be connected with related work mechanism when the rotation of needs rifle body.Like this, in jet pipe 2 blowing desulfurization agent, the rifle body also plays the mixing stirring action to molten iron and sweetening agent.
the utility model is with protecting tube 7 at spout 5 external fixation of said jet pipe 2.
for increasing mixing effect, the utility model can be fixed with blade 8 in the outside of said refractory masses 4.
The ladle and the torpedo car of desulfurizing iron all are upper opening formula containers, and furnace roof inserts spray gun has the swing space, and dynamically the Desulfurization Application of spray gun has had possibility.In identical water model test, compare with fixing spray gun, utility model people finds that rotary spray gun diminishes bubble, and ascent rate is slack-off, and ascent rate is slack-off to diminish with bubble, and blistered intensity is relevant with the track that floats.
The above is merely the preferred embodiment of the utility model , is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
